Answer: A and D
Step-by-step explanation:
Table B : not a function the value of x=3 has two images
Table C: not a function the value of x=1 has two images
Tables A and D are functions
Answer:
9.8x + 1.1y + 9.9z
Step-by-step explanation:
![\textsf {The perimeter is the sum of the side lengths.}](https://tex.z-dn.net/?f=%5Ctextsf%20%7BThe%20perimeter%20is%20the%20sum%20of%20the%20side%20lengths.%7D)
![\textsf {Hence, the perimeter is :}](https://tex.z-dn.net/?f=%5Ctextsf%20%7BHence%2C%20the%20perimeter%20is%20%3A%7D)
⇒ 5.5x + 6.2y + 4.3x + 8.3z + 1.6z - 5.1y
⇒ 9.8x + 1.1y + 9.9z
The fraction of his farm which isn’t ruined is 11/18
<h3>Fractions and proportion</h3>
Fractions are written as a ratio of two integers. The given question will be solved using the method of proportion.
If Uncle Bill has planted fruits in the farm and 7/12 is watermelon, and 2/3 of the watermelon section is ruined from the storm, the fraction ruined from the storm is;
Fraction ruined from the storm = 2/3* (7/12)
Simplify to its lowest term to have:
Fraction ruined from the storm = 7/18
Determine the fraction of the firm that is not ruined
Fraction not ruined = 1 - 7/18
Fraction not ruined = 11/18
Hence the fraction of his farm which isn’t ruined is 11/18 if uncle Bill has planted fruits in the farm and 7/12 is watermelon.
